3 安装Glance镜像服务

3.1 通过脚本安装glance服务

3.2-3.9的镜像服务的操作命令已经编写成shell脚本，通过脚本进行一键安装。如下：

# Controller 节点

执行脚本iaas-install-glance.sh进行安装

3.2 安装Glance镜像服务软件包

# yum install -y openstack-glance

3.3创建Glance数据库

#mysql -u root -p

mysql> CREATE DATABASE glance;

mysql> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'GLANCE_DBPASS';

mysql> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'GLANCE_DBPASS';

3.4配置数据库连接

# crudini --set /etc/glance/glance-api.conf database connection  mysql+pymysql://glance:$GLANCE_DBPASS@$HOST_NAME/glance

# crudini --set /etc/glance/glance-registry.conf database connection  mysql+pymysql://glance:$GLANCE_DBPASS@$HOST_NAME/glance

3.5为镜像服务创建数据库表

# su -s /bin/sh -c "glance-manage db_sync" glance

3.6创建用户

# openstack user create --domain $DOMAIN_NAME --password $GLANCE_PASS glance

# openstack role add --project service --user glance admin

 3.7配置镜像服务

# crudini --set /etc/glance/glance-api.conf database connection  mysql+pymysql://glance:$GLANCE_DBPASS@$HOST_NAME/glance
# crudini --set /etc/glance/glance-api.conf keystone_authtoken auth_uri http://$HOST_NAME:5000
# crudini --set /etc/glance/glance-api.conf keystone_authtoken auth_url http://$HOST_NAME:5000
# crudini --set /etc/glance/glance-api.conf keystone_authtoken memcached_servers  $HOST_NAME:11211
# crudini --set /etc/glance/glance-api.conf keystone_authtoken auth_type password
# crudini --set /etc/glance/glance-api.conf keystone_authtoken project_domain_name $DOMAIN_NAME
# crudini --set /etc/glance/glance-api.conf keystone_authtoken user_domain_name $DOMAIN_NAME
# crudini --set /etc/glance/glance-api.conf keystone_authtoken project_name service
# crudini --set /etc/glance/glance-api.conf keystone_authtoken username glance
# crudini --set /etc/glance/glance-api.conf keystone_authtoken password $GLANCE_PASS
# crudini --set /etc/glance/glance-api.conf paste_deploy flavor keystone
# crudini --set /etc/glance/glance-api.conf glance_store stores file,http
# crudini --set /etc/glance/glance-api.conf glance_store default_store  file
# crudini --set /etc/glance/glance-api.conf glance_store filesystem_store_datadir /var/lib/glance/images/
# crudini --set /etc/glance/glance-registry.conf database connection  mysql+pymysql://glance:$GLANCE_DBPASS@$HOST_NAME/glance
# crudini --set /etc/glance/glance-registry.conf keystone_authtoken auth_uri http://$HOST_NAME:5000
# crudini --set /etc/glance/glance-registry.conf keystone_authtoken auth_url http://$HOST_NAME:5000
# crudini --set /etc/glance/glance-registry.conf keystone_authtoken memcached_servers $HOST_NAME:11211
# crudini --set /etc/glance/glance-registry.conf keystone_authtoken auth_type password
# crudini --set /etc/glance/glance-registry.conf keystone_authtoken project_domain_name $DOMAIN_NAME
# crudini --set /etc/glance/glance-registry.conf keystone_authtoken user_domain_name $DOMAIN_NAME
# crudini --set /etc/glance/glance-registry.conf keystone_authtoken project_name service
# crudini --set /etc/glance/glance-registry.conf keystone_authtoken username glance
# crudini --set /etc/glance/glance-registry.conf keystone_authtoken password $GLANCE_PASS
# crudini --set /etc/glance/glance-registry.conf paste_deploy flavor keystone

3.8创建Endpoint和API端点

# openstack service create --name glance --description "OpenStack Image" image

# openstack endpoint create --region RegionOne image public http://$HOST_NAME:9292

# openstack endpoint create --region RegionOne image internal http://$HOST_NAME:9292

# openstack endpoint create --region RegionOne image admin http://$HOST_NAME:9292

3.9启动服务

systemctl enable openstack-glance-api.service openstack-glance-registry.service

systemctl start openstack-glance-api.service openstack-glance-registry.service

3.10上传镜像

首先下载（Wget）提供的系统镜像到本地，本次以上传CentOS_7.5_x86_64镜像为例。

可以安装Wget，从Ftp服务器上下载镜像到本地。

# source admin-openrc.sh

# glance image-create --name "CentOS7.5" --disk-format qcow2  --container-format bare --progress <       /opt/images/CentOS_7.5_x86_64_XD.qcow2
